How to Resolve \'Connection for controluser as defined in your configuration failed\' in phpMyAdmin with XAMPP?

Solve the problem of "Control user connection failed" in phpMyAdmin in XAMPP

When using XAMPP, you may encounter: "Connection for controluser as defined in your configuration failed" error. This error is usually caused by configuration issues in the phpMyAdmin installation. Here are the steps on how to resolve this issue:

1. Log in to phpMyAdmin and create a database and user:

   • Log in to phpMyAdmin using the root user.
   • Create a database named "phpmyadmin".
   • Create a user named "pma" and set "host" to the hostname or IP address of the web server (use localhost if the web server and MySQL are on the same machine). Assign a password to the new user and write it down. Grant the new user full control over the phpmyadmin database.

2. Import SQL file:

   • Navigate to the sql subdirectory in the phpMyAdmin installation directory.
   • Open the create_tables.sql file.
   • In phpMyAdmin, select the phpmyadmin database and click the "SQL" tab.
   • Copy and paste the text from create_tables.sql into the text box and execute the query.

3. Modify the phpMyAdmin configuration file:

   • Open the config.inc.php file in the phpMyAdmin installation directory.
   • Add or modify the following lines:

   <code class="php">$cfg['Servers'][1]['pmadb'] = 'phpmyadmin';
   $cfg['Servers'][1]['controluser'] = 'pma';
   $cfg['Servers'][1]['controlpass'] = '<your password>';
   
   $cfg['Servers'][1]['bookmarktable'] = 'pma_bookmark';
   $cfg['Servers'][1]['relation'] = 'pma_relation';
   $cfg['Servers'][1]['userconfig'] = 'pma_userconfig';
   $cfg['Servers'][1]['table_info'] = 'pma_table_info';
   $cfg['Servers'][1]['column_info'] = 'pma_column_info';
   $cfg['Servers'][1]['history'] = 'pma_history';
   $cfg['Servers'][1]['recent'] = 'pma_recent';
   $cfg['Servers'][1]['table_uiprefs'] = 'pma_table_uiprefs';
   $cfg['Servers'][1]['tracking'] = 'pma_tracking';
   $cfg['Servers'][1]['table_coords'] = 'pma_table_coords';
   $cfg['Servers'][1]['pdf_pages'] = 'pma_pdf_pages';
   $cfg['Servers'][1]['designer_coords'] = 'pma_designer_coords';</your></code>

4. Log out and log back in to phpMyAdmin:
